Dynarust

An opinionated DynamoDB ODM library for Rust that maps structs to native Dynamo items using serde and serde_json.

It only works with tables with a HASH key and a RANGE key, referred in the code as pk and sk. This setup can be useful for a very wide variety of use cases.

```rust use serde::{Deserialize, Serialize}; use serde_json::json;

[derive(Serialize, Deserialize)]

struct Car { brand: String, model: String, horse_power: i64 }

impl dynarust::Resource for Car { fn table() -> String { "Cars".to_string() } fn pk(&self) -> String { self.brand.clone() } fn sk(&self) -> String { self.model.clone() } }

[tokio::main]

async fn main() -> Result<()> { let client = dynarust::Client::aws().await;

let car = Car {
    brand: "Tesla",
    model: "Y",
    horse_power: 347
};

client.create(&car).await?;

client.update(&car, json!({ "horse_power": 534 })).await?;

let tesla = client.get::<Car>("Tesla", "Y").await?;

assert_eq!(tesla.unwrap().horse_power, 534)

} ```
